Question

The given graph is a representation of kinetics of a reaction.
The y and x axes for zero and first order reactions, respectively are

• A. zero order (y = concentration and x = time), first order ($y = t\frac{1}{2}$, and x = concentration)
• B. zero order (y = concentration and x = time), first order (y = rate constant and x = concentration)
• C. zero order (y = rate and x = concentration), first order ($y = t\frac{1}{2}$ and x = concentration)
• D. zero order (y = rate and x = concentration), first order (y = rate and $x = t\frac{1}{2}$)

Answer 1

Answer: (C)

zero order (y = rate and x = concentration), first order ($y = t\frac{1}{2}$ and x = concentration)

Answer 2

Zero order = Rate is independent of concentration.
First order = Half life is independent of concentration.
